If you’ve checked your Direct Messages today, you may have noticed that something’s missing: the limitation of 140 characters. You can now chat on (and on) in a single Direct Message, and likely still have some characters left over.

While Twitter is largely a public experience, Direct Messages let you have private conversations about the memes, news, movements, and events that unfold on Twitter. Each of the hundreds of millions of Tweets sent across Twitter every day is an opportunity for you to spark a conversation about what’s happening in your world.

The actions people take on Facebook—liking, commenting or sharing a post—are some of the main factors we consider to determine what to show at the top of your News Feed. We also offer the option to hide stories that you don’t want to see in News Feed. This helps us learn the kinds of stories you don’t enjoy, so we can do a better job in the future.

We want everyone to have a safe experience on Facebook. That’s why we have dedicated teams and intelligent security systems working around the clock to help keep your account secure.

We also provide optional security controls that you can turn on for added protection—you get to decide which features you want to use. Starting today, you can try a new tool called Security Checkup that makes it easier to find and use the security controls for your account.

Starting today, Windows users will have a new Twitter experience optimized especially for Windows 10. Announced last night, this Twitter app will be available alongside the launch of Windows 10 for PCs and Tablets.

The new Twitter for Windows 10 is a Universal Windows Application that gives you instant access to top Tweets, photos and videos without requiring a login. You’ll also see Tweets right out of the box in live tiles from the Start menu.

Today, we’re continuing to roll out to all users the Twitter data dashboard — a new tool to help you monitor and manage your account.

From the beginning, Twitter has empowered people to share information with the world. To put you in control of your information, we’ve made a series of deliberate design decisions that help protect your privacy and security. For example, you don’t need to use your real name on Twitter. Your privacy settings let you control whether your Tweets are kept public, and you can enablelogin verification for greater account security. We respect Do Not Track, and we secure your Twitter experience with HTTPS by default, StartTLS and forward secrecy.

Today, we’re introducing video calling in Messenger. Now you can have face-to-face conversations with your friends and the people you care about, via Messenger.

You can quickly start a video call from any conversation with just one tap. If you’re messaging with someone and realize that words just aren’t enough, you can simply choose the video icon in the top right corner of the screen and start a video call right from within an existing Messenger conversation.
